To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
 A=2πrh+2πr^2
 Where r is the radius and h is the height of the cylinder
 You have that r=15.1 inches and h=12.8 inches, then:
 A=2πrh+2r^2
 A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2 
 A=2647 in^2
 The answer is 2647 in^2

I will gove brainlist ..The line graph shows the amount of water loss in a leaking tank during 7 hours.The owner pays $1for ever
kramer

Answer:

The owner will have to pay $ 125 after 2 hours.

Step-by-step explanation:

Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :

((6000 - 5000) / 8) x 1 = X

(1000/8) x 1 = X

125 x 1 = X

125 = X

Therefore, the owner will have to pay $ 125 after 2 hours.
